Abstract
In a processing system comprising a plurality of modules, the presence of one or more modules is sensed at a control unit through the use of an analog encoder and an A/D converter. The modules terminate selected resistors in a binary resistance network in the analog encoder to produce a unique signal via the A/D converter for each combination of modules in the system. The encoder requires a minimal number of signal lines and no multiplexing of signals.
